Marble wheel car

thingiverse

This is a mini racing car designed to run on a single tiny marble that serves as the wheels, offering a smooth ride on any flat surface. Remixed from Defauld's classic "toy car" (thingiverse.com/thing:502795) The set also includes a stand-alone slider design without the body of the car for separate use. Instructions: Built with a 16mm marble in mind, this design measures 5.5cm in length and 3.5cm in width. You can easily scale it up to bigger sizes by proportionally increasing the diameter of the marble (and printing size) for bigger versions – even a massive printer can print out huge bowling ball-sized marbles! Print settings: use a low infill percentage, I recommend around 0.05%, so the marble-to-car weight ratio remains as intended. The optimal print layer height is 0.3mm for this design.
